Adaptive ghosted views for augmented reality

Mixed and Augmented Reality (ISMAR), 2013 IEEE International Symposium on, IEEE, 2013

Konferenz
In Augmented Reality (AR), ghosted views allow a viewer to ex-plore hidden structure within the real-world environment. A bodyof previous work has explored which features are suitable to sup-port the structural interplay between occluding and occluded ele-ments. However, the dynamics of AR environments pose seriouschallenges to the presentation of ghosted views. While a modelof the real world may help determine distinctive structural features,changes in appearance or illumination detriment the composition ofoccluding and occluded structure. In this paper, we present an ap-proach that considers the information value of the scene before andafter generating the ghosted view. Hereby, a contrast adjustment ofpreserved occluding features is calculated, which adaptively variestheir visual saliency within the ghosted view visualization. This al-lows us to not only preserve important features, but to also supporttheir prominence after revealing occluded structure, thus achieving a positive effect on the perception of ghosted views.

Exploring Distant Objects with Augmented Reality.

EGVE/EuroVR, 2013

Konferenz
Augmented reality (AR) enables users to retrieve additional information about the real world objects and locations.Exploring such location-based information in AR requires physical movement to different viewpoints, which maybe tiring and even infeasible when viewpoints are out of reach. In this paper, we present object-centric explorationtechniques for handheld AR that allow users to access information freely using a virtual copy metaphor to explorelarge real world objects. We evaluated our interfaces in controlled conditions and collected first experiences in areal world pilot study. Based on our findings, we put forward design recommendations that should be consideredby future generations of location-based AR browsers, 3D tourist guides, or in situated urban plannin

Head Start: Improving Academic Literature Search with Overview Visualizations based on Readership Statistics

Web Science 2013, 2013

Konferenz
At the beginning of a scientific study, it is usually quite hardto get an overview of a research field. We aim to addressthis problem of classic literature search using web data. Inthis extended abstract, we present work-in-progress on aninteractive visualization of research fields based on readershipstatistics from the social reference management systemMendeley. To that end, we use library co-occurrences as ameasure of subject similarity. In a first evaluation, we findthat the visualization covers current research areas withineducational technology but presents a view that is biasedby the characteristics of readers. With our presentation, wehope to elicit feedback from the Websci’13 audience on (1)the usefulness of the prototype, and (2) how to overcomethe aforementioned biases using collaborative constructiontechniques.

Linked Data Query Wizard: A Tabular Interface for the Semantic Web

ESWC 2013, LNCS 7882, P. Cimiano et al., Springer, Heidelberg, 2013

Konferenz
Linked Data has become an essential part of the Semantic Web. A lot of Linked Data is already available in the Linked Open Data cloud, which keeps growing due to an influx of new data from research and open government activities. However, it is still quite difficult to access this wealth of semantically enriched data directly without having in-depth knowledge about SPARQL and related semantic technologies. In this paper, we present the Linked Data Query Wizard, a prototype that provides a Linked Data interface for non-expert users, focusing on keyword search as an entry point and a tabular interface providing simple functionality for filtering and exploration.
